The present paper reports TL glow curve of Eu3+ doped Sr Y2O4 phosphor with different UV exposure time. The glow peak shows second order kinetics and evaluations of kinetic parameter were done by peak shape method. Calculations of trap depth were done with different methods and order of kinetics, activation energy and frequency factor are calculated. The recorded glow curve shifts longer temperature side with respect to UV exposure. The peaks were found 1550C, 1600C, 1640C and 1680C respectively using the heating rate 30C/s.
